Solution

It is better you use keyboard event to make changes on each time a key is pressed.I am doing using onkeyup.I prefer document.getElementById() rather than document.form because it can accurately retrieve it, every time, without caring about what happens to the document in the meantime.You can use either of the two.

JSFIDDLE

Here is the code:

function myFunction() {
  var text1 = document.getElementById("txtEmailId").value;
  var result = text1.split("@");
  document.getElementById("txtLoginname").value = result[0];
}

<form>
  Enter Email: <input type="text" id="txtEmailId" onkeyup="myFunction()" /><br/><br/> Login Name: <input type="text" id="txtLoginname" /><br/><br/>
</form>
